action of a vacuum, whereby any entrapped eifectually removed, leaving a homogeneous mass of material for further treatment.

My invention may be carried out different ways, and in its broad aspect requires that the material bein treated shall be subjected to the action og a mechanismv which, by what may be termed a filming operation, will so manipulate the mass of the same as to liberate entrapped fluids, gases, or the like, which the vacuumto rwhich it is being simultaneously subjected which when so treated will vious to the rent therein of ses, fluids,

when the vacuum is rIoken. In carryin out my invention arrange the mechanisgm `so that the 'material while bein acted'on therein will'be exposed in the orm of a thin sheet, film, skin, or the like, t0 the action of a vacuum it being provided furthermore that forms seals on VVboth'sides of the sheet,film, skin, or the like, thus rmitting an open feed of the material anni)e With the above and other o jects in view the invention consists in the described, and pointed out in the, append claims, it being understood that varlous modifications may. be made within the scope of the claims without departingfrom the or sacrificing any of the advantages o the invention. An apparatus suitable for carrying out the accompanyin which:

Referring now to the drawings designates a cyhndrical casing which is supported in horizontal position upon a frame `11. Mounted for free rotation in the casing is a feed screw 12, which will be hereinafter more fully described the feed Screw being driven from one end by a motor 13 or other prlme mover, which is operatively connectgases, etc., will be ed to the feed screw throu gear trains A and B. T necting shaft 14 of these trains is in two parts 'connected by a clutch 15 which may be thrown` out should the machine become stalled so that the motor and the first train of gears A may be started-and thenthe clutch thrown in whereby advantage may be taken of the energy of the revolving motor armature, in addition to the running torque. to start themachine.

The casing is provided at oneend with a feed hopper 16, and secured to the opposite open end of the casin is a die-head 17 wherein may be securerY a forming die for shaping the discharged material. The casing is rovided with a water jacket 18 which is fed y pipes whereby the temperature of the casing may be controlled. Furthermore, the die-head 17 is provided with a Water jacket 21 which is h two reduction ed by maiy be controlled. l referably the Water 'acket of the diehead and the water jac et of the casing a pipe 22 and drained by a pipe 23,- `whereby the temperature of the die-head e common con- 19 and drained by pipes 20, v

have no communication with each other in order that a differential of temperature may be maintained therebetween if desired, and also the water jacket of "le casing is preferablymade of independent sections or units so that it may be possible to maintain difl ferent temperatures in diiferent sections of the casing if desired.

The feed screw 12 is removably secured in the casing` upon athrust bearin -22 b means of a feather 23 and ris hol ow, the interior of the screw. conformingA approximately to the outside contour, whereby an enhanced surface is exposed to the heating heating or cooling or cooling agent, which agent is admitted through a .pipe connection cou le `the pipe connection 24,

'film, or even skin, wherebiy 24 controllableby the operator. To remove the feed screw it is simply necessary to unremove the dieead 17 from the delivery end of the machine, and then inserta suitable hook or the like inthe interior of the feed screw and withdraw the latter by suitable tackle.

The pitch of the screw in the present embodiment is shown to be substantially uniform for about one-half the length of the screw, there being near the center of the screw an obstruction either upon the screw itself or in the wall of the casing, as will be more particularly described, which obstruction causes the material to crowd in the casing and form a seal thereat. Beyond this obstruction the pitch of the screw is diminished to cause the material again to crowd and form another seal in the casing. Between these two seals the material is subjected to the action of a vacuum exerted through a pipe 25 so that an open feed, as well as an open dischar e of the material is permitted without brea ing of the vacuum.

For causin@r the material to be exposed to the action of the vacuum in a thin sheet, film, or skin, a collar 26 may be formed on the feed screw to constitute the above described obstruction, the collar causin the materiall to flow over it as a layer, the t ickness of which will be determined by the diameter of the collar, and it is preferable that the layer be relativel thin, that is, be of the approximate thic ess of` a sheet,

a large superficial area of surface an consequent extremely small cross-section of the material will be exposed to the action of the vacuum, whereby any medium such as uids, gases, light oils, moisture, air, or the like, entrapped in the material being treated will be liberated, and these will be removed bythe vacuum.

It is not essential, however, that the fihning ycollar be carried by or formed upon the screw, as it may be carried by or formed in the casing 10, one embodiment of this construction bein shown in Fig., 3, wherein thc filming colar 27 is shown as integral with the frame and projecting down into a groove 28 formed in the feed screw, there heilig channels 29 formed in the collar to allow the material to pass therethrough in the form of a thin sheet, film, or skin. To facilitate assembly of the parts of this modificationthc feed screw may be made in sections as shown.

For the purpose of observing the way the materia is-running in the apparatus, and also in assistin in cleaning out the machine back of the lining collar, sight ports 30 and a clean-out port 31 are formed in the casing as shown.

While I have illustrated a smooth bore 'to be exertedI on the material in the apin place of the vacuum, as described.

I do not limit `myself to this construction as` I ma provide projections 32 or baiiles, or the li e, to-agitate the material during its passage alon the feed screw. I may even provide ba es in the delivery opening, if desired. y i

-While I have shown a casing of uniform diameter throughout, I do not wish to limit myself to such construction, as the same may be varied in any suitable manner, as for instance, by tapering ing the same of different diameters at various points therein, or even by forming the casing of a combination of both tapering and uniform bores.

So also I do not wish to limit m self to any particular form of drive for t e feed screw since this 'may be rovided at either end or at any intermediate point and in any suitable manner. may .be similarly pitched, for both halves of its length, or the pitch of both halves may be varied, or I ma even form the feed screw of two se arate alves which may he driven separate y and their speed varied at will. Also a control of the feed or the discharge of the material, or both, may operate to controllably affect the vacuum. And I do not wish to limit myself to any particular numberof points at which the vacuum is casing,

paratus, as such vacuum may be applied at any desired number of points as experience may dictate. By providing a single discharge from the casing I am enabled to obtain an enlarged continuous discharge of material in compact vform whichmay be used, if desired, in this form, thus preserving all the advantages obtained by its submission in the apparatus to the action of thevacuum.

I also contemplate the -emplo ment of means whereby a bleedin ,to t e atmosor other differentia or controllable phere,

ressure may be utilized in addition to, or
